Start to finish these guys were the best call, from sales to service everyone was polite happy professional and knowledgeable. They got 5 windows done in under 2 Hours! They took care of our home like it was their own, cleaning up, putting cloths down etc. Our windows look absolutely stunning and we can’t wait to do the rest of our house

Nicky Sorensen

Fantastic service before, during and after installation. Short timeline from ordering to install appointment. Financing was available and that was easy too. Pricing was better than many others and the windows are made with quality. With the warranty...can't beat it!

Seldon N.

I can't say enough about this company. We had the best experience from the start of the project to the end. Alex Drechel was professional and knowledgeable. The installers, Mitch and Dan, were awesome and very friendly. Customer service was great, they were kind and patient. If I could give 10 stars, I would give 11! Thank you!

Marc R.

Universal Windows replaced all the windows in our 25-year-old house constructed from poor, builder grade materials. A simple test of placing our hands on the inside window panes in winter proved that any energy efficiency from air pocket insulation in our double panes was long ago lost, most were difficult to open, and cracks were happening. Further, the builder's decision to break our colonial house windows into 24 small panes broke up the great outside views.

C Gad

Universal Windows Direct of Manchester was fantastic! We felt comfortable with the sales representative, the office staff was communicative and the installation date worked around our schedule. The crew who installed the windows were on time (to the minute!) of the appointment, left the house clean and the windows look great! We recommend them to anyone in need of new windows.

Gus

Universal Direct Windows of Manchester installed 2 entry doors in our home and we are very happy with the doors and very impressed with the workmanship of Michael and Nick who installed the doors. Everyone that we worked with at the company was a pleasure to work with beginning with Alex who showed us and explained to us about the doors that they installed. Andrea was great to work with as far as ordering and scheduling the work. Their prices were very competitive with several other estimates that we received.

Mike Allen

Universal Windows Direct was great to work with! They completed the project in a timely manner and were quick to replace a window that had arrived broken. Everyone was friendly and helpful. Highly recommend!
